一(yi)、產品簡介
QKSG系列潛(qian)(qian)(qian)水(shui)(shui)電(dian)(dian)(dian)泵(beng)(beng)由充(chong)水(shui)(shui)式(shi)潛(qian)(qian)(qian)水(shui)(shui)電(dian)(dian)(dian)機和多級離(li)心泵(beng)(beng)組成,裝在吸罩內潛(qian)(qian)(qian)入水(shui)(shui)中工作。這種(zhong)潛(qian)(qian)(qian)水(shui)(shui)電(dian)(dian)(dian)泵(beng)(beng)較(jiao)傳統離(li)心泵(beng)(beng)和深井泵(beng)(beng)具有(you)使(shi)用(yong)維護方便,運(yun)行安全可靠,性能穩定,震動(dong)噪音(yin)小(xiao),效率高等(deng)優(you)點,改善了泵(beng)(beng)房(fang)通風散熱條件,有(you)利環保,運(yun)行費用(yong)低,可實行自(zi)動(dong)控制(zhi),對(dui)水(shui)(shui)位落差大(da)及(ji)有(you)水(shui)(shui)患威(wei)脅的地(di)方更有(you)獨特的優(you)點,由于電(dian)(dian)(dian)機工作時充(chong)滿清水(shui)(shui),在任何情況下(xia)都不會產生電(dian)(dian)(dian)火(huo)花引(yin)爆(bao)瓦(wa)斯,屬(shu)礦(kuang)用(yong)一(yi)般安全型設備(bei)。為煤(mei)炭、冶(ye)金(jin)、電(dian)(dian)(dian)力、城建、自(zi)來水(shui)(shui)及(ji)地(di)下(xia)水(shui)(shui)開發等(deng)部門(men)提供(gong)一(yi)種(zhong)新型排、取水(shui)(shui)設備(bei)。
QKSG 型潛水(shui)電泵(beng)(beng)具有兩(liang)個吸入口,將兩(liang)組(zu)葉輪(lun)背靠背地對向(xiang)(xiang)(xiang)分布(bu),實際(ji)上是兩(liang)臺多(duo)級泵(beng)(beng)并聯(lian)連接,各有其吸水(shui)口(一個在(zai)(zai)上部,一個在(zai)(zai)下部)。由(you)于兩(liang)組(zu)葉輪(lun)數量相(xiang)等、方向(xiang)(xiang)(xiang)相(xiang)反(fan),其產生的水(shui)推力(li)大(da)小相(xiang)等方向(xiang)(xiang)(xiang)相(xiang)反(fan),理(li)論上講總軸(zhou)向(xiang)(xiang)(xiang)水(shui)推力(li)為零。
QKSG-D型潛水(shui)電泵只有(you)一(yi)(yi)個吸水(shui)口,兩(liang)組葉輪(lun)也是背靠背對向(xiang)(xiang)分布。當泵揚(yang)程需葉輪(lun)總級數(shu)為偶(ou)數(shu)時(shi)(shi),每組葉輪(lun)數(shu)量(liang)相等(deng),方(fang)向(xiang)(xiang)相反,軸向(xiang)(xiang)水(shui)推力也為零(ling)。當泵揚(yang)程需葉輪(lun)級數(shu)為奇數(shu)時(shi)(shi),則下泵葉輪(lun)多一(yi)(yi)級,此時(shi)(shi)下泵末(mo)級葉輪(lun)被(bei)設計為有(you)平(ping)衡孔(kong)的(de)平(ping)衡葉輪(lun)。平(ping)衡葉輪(lun)產生(sheng)的(de)水(shui)推力,基本(ben)上(shang)(shang)被(bei)消(xiao)除(chu)。于是產生(sheng)軸向(xiang)(xiang)水(shui)推力的(de)兩(liang)組葉輪(lun)仍然數(shu)量(liang)相等(deng)、方(fang)向(xiang)(xiang)相反,總的(de)軸向(xiang)(xiang)力基本(ben)上(shang)(shang)為零(ling)。
軸(zhou)向力為零(ling),推力軸(zhou)承載荷輕,壽命長,運(yun)行可靠。是(shi)本系列潛(qian)水電泵重要技(ji)術特(te)征。
QKSG潛水電(dian)(dian)(dian)機(ji)是充水式三相異步電(dian)(dian)(dian)動機(ji),功率(lv)≥600kW時,在其(qi)轉(zhuan)子下端(duan)設有一(yi)小泵(beng)輪,它使電(dian)(dian)(dian)機(ji)內(nei)部充水循環以(yi)便對電(dian)(dian)(dian)機(ji)進行(xing)冷卻;功率(lv)<600kW時,轉(zhuan)子上帶螺旋(xuan)水槽(cao),同樣使充水循環以(yi)利(li)電(dian)(dian)(dian)機(ji)散(san)熱。本電(dian)(dian)(dian)機(ji)屬KY(礦用一(yi)般)型(xing)電(dian)(dian)(dian)機(ji),動力電(dian)(dian)(dian)纜(lan)為4芯(xin)電(dian)(dian)(dian)纜(lan),其(qi)中一(yi)芯(xin)為接地(di);信號電(dian)(dian)(dian)纜(lan)為8芯(xin)電(dian)(dian)(dian)纜(lan),其(qi)中4芯(xin)為溫度(du),2芯(xin)為水位,2芯(xin)備用。
